When I always run app to test in emulator from Eclipse , by default it never uninstalls previous one. It will maintain previous copy of database and files of the same app and ru
You can accomplish part of this using a database version in any SQLiteOpenHelper subclasses, then overriding onUpgrade to drop all tables. Actually, I suppose onUpgrade could also delete known files.
You can have a command prompt window open, and before launching, execute:
adb uninstall your.project.package
when using adb install
with the -r
modifier, the app re-installs and its data is saved. I haven't found any place in Eclipse to change this configuration, but I think this is done inside the SDK's Ant tasks. Take a look at this class for more information
Does the "Wipe user data" under run configurations target tab wipe everything for you? I'm not 100% what it wipes before running the app, but I suspect it clears out all the data. You might give it a try.
